Object Proposals

This is a library/API which can be used to generate bounding box/region proposals using a large number of the existing object proposal approaches. If you use use our library, please cite our paper:

@misc{1505.05836,
    Author = {Neelima Chavali and Harsh Agrawal and Aroma Mahendru and Dhruv Batra},
    Title = {Object-Proposal Evaluation Protocol is 'Gameable'},
    Year = {2015},
    Eprint = {arXiv:1505.05836},
}

It is fully supported on Linux and partially supported on Mac OS.
Rigor, Randomized Prim are NOT supported on Mac OS.
Rigor requires installation of boost, tbb libraries.
Geodesic Object Proposals require c++11 compiler (C++ 4.7 or higher) and eigen (3.2 or higher).

Compiling

Run compile.m

Generating Proposals

Copy over config.json.example to config.json and set imageLocation and outputLocation.
Initialize path variables.

initialize;

Generate proposals, using either of the following commands.

proposals = runObjectProposals('<proposalname>', 'path\to\image.jpg');

OR 

im = imread('path\to\image.jpg');
proposals = runObjectProposals('<proposal name>', im);

For long-running jobs, use the following command.

runObjectProposals('<proposalname>');

This will generate proposals for all the images in imageLocation and save the proposals in outputLocation.

<proposalname> is the object proposal to be run. List of possible object proposal names:

edgeBoxes [1]
endres [2]
mcg [3]
objectness [4]
rahtu [5]
randomPrim [6]
rantalankila [7]
selective_search [8]
rigor [9]
gop [10]
lpo [11]

Note

RIGOR requires boost and tbb libraries. Please follow the instructions given here to setup these libraries.

Evaluating Proposals

A ground truth file needs to be generated for the dataset. We have provided the file for PASCAL 2007 test set. The following code assumes you have generated proposals for all images in the dataset for which you want to evaluate for each proposal in your config.json file.

Evaluation using recall curves & area under recall curves

Load ground truth.

testset=load('evaluation-metrics/data/pascal_gt_data.mat');

Generate best recall candidates.

compute_best_recall_candidates(testset,configjson,'<proposalame>');

'proposalname' is an optional argument. If not provided, the function works for all the object proposals listed above.

Plot RECALL/AUC curves.

evaluateMetricForProposal('RECALL','<proposalname>');
evaluateMetricForProposal('AUC','<proposalname');

OR

evaluateMetricForProposal('RECALL');   
evaluateMetricForProposal('AUC');

Evaluation using ABO curves

Load ground truth.

testset=load('evaluation-metrics/data/pascal_gt_data.mat');

Generate best recall candidates.

compute_abo_candidates(testset,configjson);

Plot ABO curve.

evaluateMetricForProposal('ABO', '<proposalname');

OR

evaluateMetricForProposal('ABO');

Possible Issues

Linux

While running runObjectProposals('mcg'), you may get an error like
Invalid MEX-file 'path/to/ucm_mean_pb.mexa64': /matlab/path/to/libstdc++.so.6: version GLIBCXX_3.4.15' not found. This issue is explained here. Possible workaround is to start MATLAB with "LD_PRELOAD=/path/to/libstdc++.so.6 matlab". Replace /path/to/libstdc++.so.6 with the system install location for libstdc++, usually something like /usr/lib/x86_64-linux-gnu/libstdc++.so.6.
